Red List Index (reef-building corals) [BIP]
Indicator description
This version of the Red List Index is based only on data for reef-building coral species, and shows changes in the aggregate extinction risk of these species over time. The decline in the Red List Index for reef-building corals indicates that ecosystems supporting them are not currently being adequately safeguarded. There are a multitude of possible reasons for this decline, including climate change and ocean acidification, as well as unsustainable fishing practices.
